| 11. | The only standard across engineering workshop drawings is in the creation of orthographic projections and cross section views.
|
| 12. | The simplest projection, the orthographic projection, simply involves removing the z component from transformed 3d vertices.
|
| 13. | Like the stereographic projection and gnomonic projection, orthographic projection is a distorted, particularly near the edges.
|
| 14. | There are many possible orthographic projections that can show the cross-polytopes as 2-dimensional graphs.
|
| 15. | The tetrahedron-first orthographic projection of the tetrahedral prism into 3D space has a tetrahedral projection envelope.
|
| 16. | Coxeter's famous book on polytopes ( Coxeter, 1948 ) has some examples of such orthographic projections.
|
| 17. | Common names for orthographic projections include plane, cross-section, bird's-eye, and elevation.
|
| 18. | Telecentric lenses, on the other hand, provide an orthographic projection, providing the same magnification at all distances.
|
| 19. | The Klein model is an orthographic projection to the hemisphere model while the Poincar?disk model is a stereographic projection.
|
| 20. | The triangular-prism-first orthographic projection of the octahedral prism into 3D space has a hexagonal prismic envelope.
